Physical properties
Hardness of 6-7 on the Mohs scale, colors range from pink to gray depending on its chemistry, luster is dull to vitreous, phaneritic crystal structure, specific gravity is 2.65 to 2.75.
Formation & geological history
Formed from the slow crystallization of magma below Earth's surface over millions of years, typically found in continental crust.
Uses & applications
Widely used in construction for countertops, flooring, monuments, and curbing due to its high durability.
Geological facts
Granite is the most common intrusive rock in the Earth's continental crust and is frequently used as a benchmark for architectural durability.
Field identification & locations
Easily identified by its visible interlocking crystals of quartz, feldspar, and mica; found globally in mountainous regions and shield areas.
